I think we'd need to know more about your style of bowling and lane conditions you see on a regular basis to make any type of intelligent suggestions. Normally I see people requesting 2-3" pins with a top weight of around 2.5-3oz. If you get any ball with those specs - you can just about drill it anyway you want to and have it work well.
Having said that, several on here have said that the Black Diamond is an extremely strong ball, so that's why more info about how you bowl would be needed.
